Abstract: A cooling system for the electrical components compartment of an automatic bowling pin spotter having a low power subcompartment and a high power subcompartment, includes an upwardly projecting chimney structure which supports a fan. The fan forces air flow from the ambient environment through the low power subcompartment and then through the high power subcompartment of the pin spotter, over a generally U-shaped path, in order to remove heated air from within the subcompartments with only one pass of the air therethrough. A plurality of openings in the hood, partitioned from the chimney structure, permits the heated air to exit into the ambient environment thereby maintaining a cool operating temperature within the compartment. Filtering screens are also provided to minimize the introduction of foreign particles into the interior of the electrical components compartment.
